Age-specific percentile-based reference curve of serum procalcitonin concentrations in Japanese preterm infants Noriko Fukuzumi1,*, Kayo Osawa2,3,*, Itsuko Sato1, Sota Iwatani4, Ruri Ishino1, Nobuhide Hayashi1, Kazumoto Iijima4, Jun Saegusa1 & Ichiro Morioka3,4 Procalcitonin (PCT) levels are elevated early after birth in newborn infants; however, the physiological features and reference of serum PCT concentrations have not been fully studied in preterm infants. The aims of the current study were to establish an age-specific percentile-based reference curve of serum PCT concentrations in preterm infants and determine the features. The PCT concentration peaked in infants at 1 day old and decreased thereafter. At 1 day old, serum PCT concentrations in preterm infants
